Chapter 14 - Shock

What are the four main types of shock? Shift+enter

Hypovolemic
Cardiogenic
Obstructive
Distributive

BLS & AEMT shock treatment

O2
Blanket
Rapid transport
Fluids

What’s the first step in treatment priorities? NOT O2

XABCs

Two types of hypovolemic shock

Hemorrhagic
Non-hemorrhagic

Three types of non-hemorrhagic hypovolemic shock

Burns
Emesis
Diarrhea

Three examples of cardiogenic shock (abbreviations)

MI
CHF
Arrythmia

Three examples of obstructive shock (no abbreviations)

Pulmonary Edema
Tension Pneumothorax
Cardiac Tamponade

What is the definitive treatment for pulmonary embolism

Thrombectomy or fibrinolytic therapy

What is the definitive treatment for a tension pneumo

Needle thoracostomy and/or chest tube placement

What is the definitive treatment for cardiac tamponade

Pericardiocentesis

Types of distributive shock

Anaphylactic
Septic
Neurogenic
Psychogenic

What does MAP stand for

Mean Arterial Pressure

How do you calculate MAP

Diastolic BP + 1/3 pulse pressure

How do you calculate pulse pressure

Diastolic - systolic BP

What MAP is needed to “stay alive”

65

Three stages of shock

Compensative
Decompensated
Irreversible

Shock definition

Inadequate tissue perfusion

Perfusion definition

Adequate oxygenated blood supply to a tissue or organ

Ischemia definition

Lack of perfusion to an organ/tissue causing temporary damage

Infarct definition

Tissue death resulting from prolonged ischemia
